one fish, two fish

The fish were not able to directly count over four, but they were able to distinguish between larger numbers if they differed by a ratio of 2:1.

For example, the fish could distinguish between a shoal of 16, compared to a shoal of eight others. But they could not tell the difference between a shoal of 12 compared to a shoal of eight, a ratio of 3:2. This demonstrates that fish are able to visually estimate larger numbers - but not very accurately.
